I see the "hacker guild" term used often and in many threads, all of which (threads) have a title not related to it, so i didnt figure out a good place to post this.

My questions are:
1- "Hacker guilds", are they referred to as that because they are created by a hacker or because their members are hackers?
2- I have read a fair bit of threads about hackers and the most common types in MW and CC forums where i originate from, and i am under the impression that:
-wars are won by collecting CP ------> CP is collected by hitting and spending energy -------> energy is restored by using gems ------> gems are bought or earned through tapjoy ------> no hackers have managed to get gems by hacking.

....ah the question. Yes....
How do hacker guilds earn significant advantage during the guild wars if they can not gain gems=CP illegaly?
